Dr. Wayne King of Lawrence Livermore National Labs will speak at ADAPT/Colorado School of Mines on Nov. 8 from 4 to 5:50 pm in Brown Hall on the topic Simulation And Modeling Of The Metal Powder Bed Fusion Additive Manufacturing Process

Wayne King currently serves as Project Leader of the Accelerated Certification of Additively Manufactured Metals Project at LLNL (http://acamm.llnl.gov/). This project is focused on developing physics-based models relating microstructure, properties, and process to performance of materials and includes predictive models for the laser powder bed fusion process. The project also focuses on using integrated in-process sensing, monitoring, and control technologies to accelerate part qualification.
He and colleagues were recently published on Simulation And Modeling Of The Metal Powder Bed Fusion Additive Manufacturing Process and Metal powder absorptivity: modeling and experiment.
Qualification of parts produced using laser powder bed fusion additive manufacturing is broadly recognized as a significant challenge. Physics-based models have been identified as being foundational to qualification of AM metal parts. In this presentation, we discuss a multiscale modeling. This includes a model at the scale of the powder that simulates single track/single-multi layer builds, and provides powder bed and melt pool thermal data. A second model computationally builds a complete part and predicts manufactured properties (residual stress, dimensional accuracy) in 3D. Modeling is underpinned by extensive experimental validation and is tied to experiment through data mining.
This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. This work was funded by the Laboratory Directed Research and Development Program at LLNL under project tracking code 13-SI-002.

About ADAPT - the Alliance for the Development of Additive Processing Technologies
The Alliance for the Development of Additive Processing Technologies (ADAPT) is a research and development organization dedicated to the creation of next-generation data informatics and advanced characterization technologies for additive manufacturing technologies. ADAPT uses these tools to help industry and government qualify, standardize, assess, and optimize advanced manufacturing processes and parts. Several levels of membership to the ADAPT consortium are available. Founding industry members include Ball Aerospace & Technologies Corp., Faustson Tool, Lockheed Martin, Citrine Informatics. Grant funding from the Colorado Office of Economic Development & International Trade (OEDIT) was provided to Manufacturer’s Edge and The National Institute of Standards and Technology’s Hollings Manufacturing Extension Partnership.
